Service level agreement in optical networks

Contrat de Niveau Service Dans les Réseaux Optiques

Abstract

This article proposes a Service Level Agreement applied to the optical domain (O-sla), which is expected to be the near and long term network technology thanks, among other things, to the great bandwidth capacity offered by optical devices. After an exposition of the rationale behind an optical sla, parameters which could enter in thisO-sla, as well as their values for four classes of services, are proposed. Different client (wavelength or sub-wavelength) and services types (from leased wavelength to bandwidth on demand) are distinguished when necessary.

Résumé

Cet article propose un Contrat de Niveau Service appliqué au domaine optique. Ce dernier est sensé être la future technologie réseau à court et long terme grâce, entre autres, à la grande capacité en bande passante offerte par les routeurs optiques. Après avoir démontré le besoin en Contrat de Niveau Service dans un réseau optique, nous proposerons des paramètres qui pourraient constituer la Spécification de Niveau Service (Sls) optique, ainsi que leurs valeurs pour quatre classes de services. Nous distinguons, lorsque nécessaire, différents types de clients (longueur d’onde et sous-longueur d’onde) et différents types de services (de la longueur d’onde laissée à la bande passante à la demande).
